Download Raspberry Pi Imager 2.0.2

✨ Features
Performance
- Add direct I/O bypass for Linux (O_DIRECT), macOS (F_NOCACHE), and Windows (FILE_FLAG_NO_BUFFERING) to reduce memory pressure during writes
- Add zero-copy ring buffer for data transfer between download and write threads, reducing CPU overhead
- Add asynchronous cache file writer to overlap download and disk I/O operations
- Dynamically adjust write queue depth based on available system memory, tuned for more aggressive performance
- Add sequential read hints (FADV_SEQUENTIAL, F_RDAHEAD) during verification for better prefetching
- Track detailed performance metrics for network, decompression, and write phases
- Use Windows IOCTLs (IOCTL_DISK_DELETE_DRIVE_LAYOUT) for faster disk preparation instead of diskpart
- Add performance data analysis tool for debugging slow writes (Press CTRL + SHIFT + P, save the JSON, attach to a new Issue).
Drive Handling
- Switch drive polling from fixed 1-second interval to adaptive mode (fast during selection, paused during writes)
- Fix NVMe namespace detection on Linux to correctly identify NVMe drives by parsing /sys/class/nvme/
- Suppress Windows "Insert a disk" error dialog when accessing empty removable drives
- Fix macOS APFS volume handling to correctly identify child partitions
- Allow virtual disks to be treated as 'system' drives on Windows & Linux (macOS was supported from 2.0.0)
User Interface
- Add password field component with show/hide toggle button
- Add type-to-search in combo boxes with backspace support to delete characters
- Add Enter key to open combo box dropdown when focused
- Show device and OS names with tooltips when text is truncated
- Restructure countdown timer before write confirmation dialog can be accepted
- Fix bottom padding in write confirmation dialog
- Reintroduce multiple SSH key support
Accessibility
- Add proper focus order and keyboard navigation for screen readers across all dialogs
- Move accessibility description properties to centralized form label component
macOS
- Add file type filter popup to native save dialogs (matching Finder behavior)
- Request location permission asynchronously to avoid blocking the UI when detecting WiFi networks
- Add dark mode, tinted and clear Liquid Glass icon variants using Icon Composer for proper menu bar appearance
Linux
- Fix X11 authorization when running AppImage as root via xhost and proper XAUTHORITY handling
- Install scalable SVG icon instead of fixed-size PNG for better HiDPI support
Windows
- Migrate file dialogs from legacy GetOpenFileName API to modern IFileDialog COM interface
- Fix file dialog filter string requiring double-null termination
- Fix scroll direction on ImComboBox
Customization
- Allow SSH public key authentication without requiring a username/password to be set
- Fix missing user creation block when not enabling SSH
Networking
- Add automatic fallback from HTTP/2 to HTTP/1.1 after repeated failures
- Log HTTP protocol version used on successful downloads
- Skip error dialogs when user cancels download mid-transfer
- Properly close file handles when operations are cancelled
Other
- Add file logging support (--log-file command line argument)
- Re-use ring buffer memory for SHA256 verification instead of allocating new buffers
- Validate init_format field in OS list JSON and log warnings for invalid entries
- Extract clean version string (X.Y.Z) for telemetry instead of full build string
- Add privilege escalation support for elevatable application bundles
🐛 Bug Fixes
- Fix SSH key file dialog filter on Windows (was passing list instead of string)
- Fix Italian translation inconsistencies
- Fix icon installation path for Linux desktop integration
- Fix cloud-init user-data generation for Pi Connect configuration
- Remove O_SYNC flag from file operations (was causing unnecessary performance penalty)
